If you have HAL's Internet download features enabled, in particular TV Listings, then it is normal to see HAL pop up an Internet Maintenance
screen at times. The maintenance message means that HAL is removing old unneeded TV Listing information. This keeps your TV Listing files from getting too large. The maintenance may take a few minutes depending on the type of TV listings you are receiving.
Normally the Internet maintenance happens around 3am when there is less likely to be any computer activity. You may also see this occasionally when HAL is starting -- this will happen if HAL was not running at the time that maintenance should have occurred.
If you are seeing the maintenance staying on the screen for longer then a few minutes, or it does not go away at all, then there may be a problem.
